"And how long could you have kept afloat if the fog had not lifted?" he
inquired with gentle sarcasm. To which, adroitly adjusting hair and
kerchief, she made no answer. So he added: "There is supposed to be a
difference between mature courage and the fool-hardiness of the
unfledged--"

"What?"

The quick close-clipped question cutting his own words silenced him.
And, as he made no reply, she continued to twist the red kerchief around
her hair, and to knot it securely, her doubtful glance returning once or
twice to his amused face.

When all had been made fast and secure she rested one arm on the gunwale
and dropped the other across her knees, relaxing in every muscle a
moment before departure. And, somehow, to Hamil, the unconscious grace
of the attitude suggested the "Resting Hermes"--that sculptured
concentration of suspended motion.

"You had better not go just yet," he said, pointing seaward.

She also had been watching the same thing that he was now looking at, a
thin haze which again became apparent over the Gulf-stream.

"Do you think it will thicken?" she asked.

"I don't know; you had a close call last time--"

"There was no danger."
